Interesting approach.  I have the opposite problem.  House is so tight I can't get the humidity out (never needed a humidifier), hence the recent install of an HRV.  Hoping to write some code so it turns on when humidity is high. I use an HAI RC2000 Thermostat and would like to us its humidity...

I have just purchased a dehumidifier in hopes of managing some high humidity issues during the cold winter months.  Wrestling with the most efficient program to run it.  Appreciate any advice on programming blocks for annual humidifying and dehumifying taking into account our cold Canadian...

Hi Folks, hoping to get some advice on the best way to wire up a SM120 into my omnipro.  I realize some of the risks associated with the SM120 (particularily in the event of a 120V power failure) but this will be used to compliment existing 4wire 12V smokes (possibly crosszoning).    I was going...
